Problems in calculating fixed-tube-sheet heat exchangers using SW6
Thread Content
I’m a complete beginner when it comes to pressure vessels, and I have a question for the teachers and experienced professionals here. When using SW6 to calculate fixed-shell plate heat exchangers, the shell side consists of a single shell layer without any shell partition. When calculating the plate structure, what value should be entered for the \"groove depth on the shell side\"? Is it unnecessary to enter any value, or should the groove depth for a welded structure, which is 3 mm, be entered instead? I would appreciate the guidance from all teachers and seniors
During design, the depth of the shell-side grooves is determined based on these welding joints specified in GB/T151.
Thank you for your reply. I have another question: for the sixth type shown in the diagram, should I enter ‘h’ or the depth of the circular arc?
Enter the depth of arc R; use ‘h’ for a more conservative value.
